PAPER ROLL HOLDER Filed Nov. 24, 1967 Fig] PRIOR I //VVE/V70R.S James M. Shaver Joseph E. McCann United States Patent US. Cl. 242-552 9 Claims ABSTRACT OF THE DISCLOSURE An improved paper roll holder wherein the improvement is a lock in combination therewith comprising a slide, spring locking means for said slide, and slide stop means; said lock having utility to prevent removal of the paper roll until all paper has been used on the roll.

Our invention relates to a lock for and in combination with a paper roll holder, :and it is an improvement in paper roll holders such as described in US. Patent No. 2,372,949. Such holders are used particularly in public buildings, institutions, schools, and the like.

A problem that evolved, particularly in public schools, with the use of holders such as described in the above US. patent was that such holders are extremely vulnerable to vandalism. The prior art holder, as shown in FIGURE 1, needed only to have the male mate 1 unsnapped from female mate 2 in order to remove a new or partially used roll of paper therefrom. When removed, the paper was wantonly wasted, such as throwing streamers thereof from building windows by school children. Obviously in this age of requiring utmost economics, particularly in our school systems, the need of a solution to such wanton waste as above was imperative, and our invention evolved as a result of the above problem.

A principal object of our invention is to provide a paper roll holder having a, reliable locking means to prevent removal of the paper prior to exhaustion of the paper.

A further object of our invention is to provide an inexpensive, destruction free paper roll holder having a reliable locking means.

Other objects of our invention will be obvious and will appear from the specification hereinafter set forth.

FIGURE 1 is a view of the prior art paper roll holder.

FIGURE 2 is a view of our improved holder with locking means.

FIGURE 3 is a view of our improved holder in the open position with the slide forward and the spring in the locking position.

FIGURE 4 is a view showing the slide being pushed to the open position and the spring in the depressed unlocked position.

FIGURE 5 is a View showing the utility of the holder.

FIGURE 6 is a view of the male and female latching tongues.

Our invention and FIGURES in detail as follows:

FIGURE 1 shows the prior art paper roll holder comprising a hinged arm 5, hinge 3, fixed arm 6, male latching tongue 1, female latching tongue 2 (the male and female tongues are shown in detail in FIGURE 6) and mounting holes 4. To insert a roll of paper on this holder it is simply necessary to depress arm 6 slightly, there is suflicient resiliency in the arm to permit this, to disengage the snap type of latching, swing arm 5 outward by the hinged means 3, slip a roll of paper over arm 5, swing arm 5 closed, and snap male tongue 1 into latching engagement with female tongue 2 to be utilized as shown in FIGURE 5 wherein 11 is the holder and 12 the paper roll. It is a simple matter to remove the paper roll at any time by 1-6 will now be described 3,454,236 Patented July 8, 1969 ice simply depressing arm 6 to disengage arm 5 from arm 6. While the male tongue side of the holder is shown as hinged, this holder would operate in the same manner if the female side were hinged and the male side fixed.

FIGURES 2, 3, and 4 show in detail our improvement over the prior art holder described above. Holder 11 in FIGURE 2 operates in the same manner as the holder described in FIGURE 1 above regarding the insertion of the paper roll and snap latching male tongue 1 into female tongue 2. However, after the snap latching step, slide 7, which is against stops 10 when paper roll 12 is inserted on arm 5, is moved toward the movable hinged arm 5 to a final position where it engages both movable arm 5 and fixed arm 6 and is over male tongue 1 and female tongue 2. In this final position, spring 8, which is mounted in arm 6 by means of pop-rivet 9, is released from its depressed position, as shown in FIG- URES 2 and 4, to a locked position, as shown in FIGURE 3, which prevents slide 7 from being moved back from the final position. In the locked position, with a roll of paper on the holder, it is impossible to depress spring 8 and unlatch male tongue 1 from female tongue 2 until all of the paper on the roll has been exhausted. When the paper has been exhausted, the paper core is cut by any convenient cutting tool, the spring can then be depressed, the slide returned to the original position abutting stops 10, and the holder opened as described regarding FIG- URE 1 above. The stops 10 are formed by making arm 6 of a first portion and a second portion with the second portion adjacent to tongue 2 being of a more narrow dimension than the first arm portion. While FIGURE 2 shows male tongue arm 5 as hinged, the device would operate equally as well if the male arm were the female arm and vice versa.

We claim:

1. A paper roll holder comprising a first movable arm, a second fixed arm, movement means for rendering said first arm movable and for connecting said first arm to said second arm, holder mounting means located on said fixed arm, first engaging means located at the end of the movable arm opposite to the end of said movable arm where the movement means is located, second engaging means located at the end of the fixed arm opposite to the end of said fixed arm where the movement means is located, said fixed arm having a first portion of a first dimension and a second portion of a second lesser dimension, said second portion being located adjacent the second engaging means, channel shaped slide means located in a sliding manner on said second portion of said fixed arm, stop means for said slide means extending between said first and second fixed arm portions, spring means fixedly mounted on said fixed arm for locking said slide means in a position to prevent the disengagement of said first engaging means from said second engaging means, and fastener spring mounting means for mounting said spring means on said fixed arm.
